IMPROVEMENT IN GUIDES FOR CREASING TUCKS AND PLAlTS PREPARATORY T0SEWING.

Specification forming part of Letters Patent No. 34.357, dated February11, 1862.

To all whom it may concern:

Be it known that I, WARREN L. FISH, of Newark, in the county of Essexand State of New Jersey, have invented a new Apparatus for Urea-sin gTucks and Plaits Preparatory to Sewing; and I do hereby declare that thefollowingis a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, forming part of thisspecification, in which- Figure 1 is a side view of the apparatus. Fig.2 is a front view of the same. Fig. 3 is a plan of the same. Fig. 4exhibits portions of the creasing-rollers and other parts of theapparatus. Fig. 5 is a top view of a modification of part of theapparatus. Fig. 6 is-a side view of the same.

Similar letters of referenceindicate corresponding parts in the severalfigures.

This apparatus is designed for creasing cloth in the proper lines forthe folding of tucks and plaits either to be sewed by hand or by asewing-machine, and in either case may be entirely separate fromthesewing-niachine,though it may be attached thereto when desirable.

To enable others skilled in the art to fully understand and construct myinvention, I will proceed to describe it with reference to the drawings.

A is a plate which forms the base of the apparatus, and to which all itsworking parts are attached, intended to be attached by a clamp orpermanently secured to a table or to the stand of a sewing-machine or toany other suitable support.

B is a fixed arm secured to the plate A on the top of and near the rearend thereof, and extending over the table nearly to the front thereof.To the top of this arm is firmly secured a spring, a, the front portionof which is made to constitute a horizontal or nearly horizontal axlefor the grooved creasing-roller B, which is fitted to rotate freelythereon, and to the bottom of the same arm are secured two springs, b b,which constitute elastic bearings for the journals of a long roller, 0,which is grooved both longitudinally and spirally to produce upon it aspiral system of teeth, said roller and bearings being so arranged thatthe roller occupies a position parallel, or nearly so, with the axis ofthe roller B,and will press on any material that is laid upon the plateA.

D is a fixed arm secured to the plate A at the bottom, near the rear endthereof, and extending forward in the form of an inverted bow to a pointsome distance in front of the plate A, from whence it turns back in ahorizontal direction to constitute an axle, c, for the edgedcreasing-roller D, the upper part of whose edge or periphery is slightlyabove the upper surface of the plate A, the said axle 0 being parallelwith the axle a and roller 0.

The grooved roller B is situated directly over the roller D, so that itsgroove matches with the edge of D, and it is held down upon or toward Dby the elasticity of its axle a.

E is the guide fitted to the sides of the plate A, and standing up aboveand perpendicular to the said plate, but having its face oblique to theaxis of the rollers B, O, and D, as shown in Fig. 3, in such a directionthat the material to be creased by the rollers B D, moving at rightangles to the axis of B, U, and D in the proper direction, would moveslightly toward the said face. The direction in which the material movesto be creased is indicatedin Fig. 3 by an arrow.

The said guide E has an opening for the passage of the roller 0, arm B,and axle a. It is attached to a rod, 61, which is fitted to slidethrough an upright stud, F, secured to the plate A, for the purpose ofadjusting the guide at various distances from the creasingrollers B D,according to the depth or width or distance apart required for the tucksor plaits, and the said stud F is fitted with a bindingscrew, 0, tosecure the guide in the required position.

Near that side of the guide on which the material enters the apparatusthere is attached a straight rod,f, which stands out in a forwarddirection parallel with the rollers G and axles B D, to smooth thematerial as it passes to the creasing-rollers.

Gr is a lever attached to the arm B, for raising the axle a and rollerB.

c'j his the guard, consisting of a light arm, 6, attached to the arm Bon the side from whence the material passes between thecreasing-rollers, and carrying at its ends two prongs, which partlyencircle the roller D, and the upper one, In, of which is so arranged asto support the material entering between the two creasing-rollers.

The operation of the apparatus is as follows: The guideE having beenadjusted to the proper distance from the creasing-rollers, the materialto be creased is introduced between the guide 2' 7a and the bar f, andpassed over the plate A, under the roller 0, and between thecreasing-rollers B D, with its edge against the guide E, and is thendrawn by hand or otherwisein the direction of the arrow shown in Fig. 1,the part entering betweenfand 6 It; being in the meantime held upagainstf to be smoothed out. As the material 1s drawn between therollers B D the roller G keeps the cloth flat upon the plate A, and bymeans of its spirally'arranged teeth exerts a constant tendency to keepthe edge against the guide,

so that the creasingrollers will crease the material in a line parallelwith the edge. After folding the cloth in the crease produced, thefolded edge is placed against the guide E to do the next creasing, thusgaging the tucks or plaits one from another. The stitching of the tucksor plaits may be performed after erery preventing the said axle c frominterfering with the passage of that portion of the material, andallowing the said portion to pass awaywithout interfering with theportion on the plate'A by which the gaging is performed, or the portionwhich has not yet been creased, as will be understood by reference toFigs. 1 and 4, Where i represents the material which has been creased, mthe folded portion by which the gaging is effected, and n the uncreasedportion.

Though I prefer to use rollers B D for creasing, fixed surfacespresenting a similar groove and edge may be used successfully as theequivalent of such rollers.

A flat plate, H, serrated, as shown in Figs. 5 and 6, may be used as theequivalent of the roller 0. This plate is arranged above the plate A topress upon the cloth in a similar manner to the roller 0.

The teeth 19 p are on the opposite edge of the plate to that onwhichvthe cloth enters beneath it, and the said teeth have their pointsinclined slightly toward the' guide E" and beveledon their under sides,as shown in Fig. 6 and by the dotted lines in Fig. 5.

What I claim as my invention, and desire to secure by Letters Patent,is- The com binatioti of the rollers B D with th adjustable guideE androller O,as and for the purpose herein shown and described.
